WINDIVIILL.

SPECIFICATION forming part of Letters Patent No. 415,811, dated November 26, 1889.

Application filed July 10, 1889. Seal No. 317,047. (No model.)

To all whom it may con/cern.-

Be it known that I, CHARLES CLAYrooL, a citizen of the United States of America, residing at Spencer, in the county of Clay and State of Iowa, have invented certain new and useful Improvements in IVindmills, of which the following is a specification, reference being had therein to the accompanying drawings. A

My invention relates to machines designed to overcome the dead-centers in wind-pumps or other mechanisms operated by windwheels; and it consists in certain improvements in construction, hereinafter described and claimed.

In the accompanying drawings, Figure l is a front view. of the machine; Fig. 2, a sectional view showing the pawl-and-ratchet mechanism and device for throwing. the machine out of gear, and Fig. an end View of the parts shown in Fig. 2.

Similarletters referto Similar parts throughout the several views. 1

A represents a spur-wheel the rim of which is attached or cast to the sides of the spokes and its inner circumference ratcheted, as shown in Fig. 1. Meshing with the spurwheel is a pinion B, mounted upon the shaft b, which revolves in bearings in the supporting-frame C. Mounted upon the shaft b is a pulley D, connected by a belt E with a smaller pulley F, mounted upon the shaft f. Upon the outer end of the shaft Z) is mounted a flywheel G. The shaft f is also adapted at its outer end to tit the fly-wheel G, so that the latter may be mounted upon either shaft, according to the velocit-y of the wind1nill, thus securing at all times a steady and uniform motion of the machine. Upon the shaft of the spur-wheel A are loosely mounted the two arms I-I II, each of which has at its outer end a guide I, consisting of two pieces with projecting flanges adapted to inclose the ratchet-teeth upon the inner circumference of the Spur-wheel and hold the pawl .I in position, the latter being` pivoted between the two sections of the guide, as shown in Fig. 3. Each of the pawls J J is attached to its pivotpin, which passes through and proJects beyond the face of the guide. Upon one end of the pivot-pin is loosely mounted the bent arm M, having at its outer end a weighted ball, and upon the pivot-piiroutside of the arm M is a Shoulder N, with two projecting' arms n n', adapted to engage with the outer end of the bent arm M. It will be seen that when the weighted arm M, rest against the arms n the pawls will be held against the ratchetteeth; but if the arms M are turned so as to rest against the arms n the pawls will be disengaged and the machine thrown out of gear. The arms H II are pivoted to the connectingrods K K', one of which is pivoted to the reciprocating shaft L above the spur-wheel and the other pivoted to the reciprocating shaft below thespur-wheel at such position as to bring the guides I I to the upper part of the Spur-wheel and about one-fourth of its circumference distant from each other when the reciprocating shaft is at the upper end of its stroke. As the reciprocating shaftL makes its downward stroke it carries the connectingrods K K down, and the pawl J will engage the ratchet-teeth and cause the spur-wheel to revolve, While the other pawlJ will pass over the ratchet-teeth without engaging them,- so that when the reciprocating shaft reaches the end of the stroke the guides I I will be at the lower side of the spur-wheel. As the'reciprocating shaft makes its upward stroke, carrying the rods K K upward, the pawl .I will engage the ratchet-teeth and complete the revolution of the spur-wheel, while the other pawl J will pass over the ratchet-teeth until the upper end of the stroke is reached. In this way the perpendicular motion of the reciprocating shaft is converted into circular motion, the spur-wheel revolving continually from right to left. The rate of speed imparted to the spur-wheel by a stroke ofthe reciprocating shaft depends upon the length of the arc traversed by the pawl, and if the connectingrods are pivoted to the arms II H near the shaft of the spur-wheel the speed of the latter will be greater than where the rods are pivoted to the outer ends of the arms..

I am aware of the United States Patent No. 192,623 to C. Hammelmann, and VI do not claim as my invention anything shown or claimed in said patent; but

lVhat I claim, and desire to secure by Letters Patent, is-

IOO

The combination, with the spur-Wheel A, is provided with a shoulder N, and the bent haViugratchet-teeth upon its inner periphery, arms IVI M, Weighted at their outer ends and the arms I-I II', pivoted upon the shaft of the loosely mounted upon said pivot-pins, as and spur-Wheel and provided at their outer ends for the purposes specified.
